It is extremely difficult. Transforming a male to a female voice is
*far* more than just upping the frequency; the very shape of the cavity
used for sound production is different (because of the second laryngeal
drop that males experience that causes the voice to break), so to get it
right you need to reverse the sound back to the laryngeal oscillations
that created it, repeat them in a female larynx/throat configuration and
run the model forward again in there.

This is *rather* computationally expensive ;)
